Hello :
<span>f(x) = 6 – 5x and g(x) = 4x – 1
f(x)-g(x) = 6-5x-(4x-1) = 6-5x-4x+1 = -9x+7
whene x = - 2
f(x)-g(x) = -9(-2)+7 = 25......(answer : D)</span>
Answer:
You should add 4 to both sides because that would make the left side a perfect square which is what you are intending to do when you complete the square.
D. is the correct answer.

Answer:
6 1/4
Step-by-step explanation:
Add up the fabric that she has
3 1/2 + 6 3/4
Get a common denominator
3 2/4 + 6 3/4
9 5/4
9 4/4 + 1/4
10 1/4
Subtract this from the fabric that she needs
16 1/2 - 10 1/4
Get a common denominator
16 2/4 - 10 1/4
6 1/4
